can't set storage_class to inherit the source object in replication rules

[NoaBM]

Describe the Bug

When creating s3 bucket with s3_replication_rules, the storage_class inside destination is always enabled as "STANDARD" and can't be set to null, when the null should use the source replication bucket.

Expected Behavior

storage_class for replication should not be set, and should be taken from the source replication bucket.

Steps to Reproduce

call the module with all relevant fields including the replication fields -

module "s3_bucket" {
    source                  = "cloudposse/s3-bucket/aws"
    version                 = "4.0.1"
    s3_replication_rules = [{
         destination = {
              storage_class = null
          }
     }]
}

see in aws console that the "Destination storage class" is set to Standard and not as it should be unmarked.

Environment

• Terraform version - 1.5
• module version - 4.0.1

Additional Context

I tested a fix to the module in variables.tf line 267 and changed it to - storage_class = optional(string, null), and it seems to work either if :

• we don't send "storage_class" to the module at all, the result is inherited from the source bucket

• we do send "storage_class = STANDARD" it's sets it to standard.
